How does the filter work?

1. If I select "no favorite filter", I suppose I should see all the tasks of the current project (with start and end dates), right? But I cannot see all actually. For example none of the tasks assigned to me show up.

2. If I select a filter: project = "[the current project]", I get the same result as above

3. if I select "assignee = currentuser", I do see my tasks. (All my tasks are within the current project)

4. If I select a filter: assignee = currentuser or project = "[the current project]", which actually has the same effect as the filter in #1 and #2 as I only work within the current project, I get more tasks appear in the gantt chart than #1 and #2, but I still don't see those tasks assigned to me.
